Jesus Christ...but according to the history of china is a completely unification history on earth which once they have power they will expanding non stop. they will attamp to conquer the planet and complete its destiny of unification and in tern of unification means they will force to kill or assimilize the people or race they conquer...in that time we will have to speak chinese and eat with chopstick......because mostly of tragic past in 19th century i dont think they will spare any of us alive....(most of them having extremely hatred with europeans..you will know what would happan..)and mostly many generation of chinese leader always want to remain their name in history that no one will know what kind madness they will do.
accordding to wikipadia the china once have many race resided on it before the china been unified.(nicro, caucasian, mongols, huns and mostly veitnamese in south china) where they go?? they extincted...(still many of chinese people believe that the world will eventually unify by china! and it is in modern day!)
you will be disappointed.... chinese people was based on the needed of subface space that they can maintain their population and breed more. they will not allow any indepandent state exist once they having power.
PS: i dont think even their communist government could control the ideal that its own people believe..and soon overthrow it by its own people in the future once it's under control..(the birth control has achiving the rebel every year)

Historically, China was very isolationist. In any case, the link you gave us refers to China being unified as one country, not China unifying the entire earth under one country. You need to stop making **** up.
